COVER.

. Application filed April 14,

To all whom it may concern:

Be it known that I, ARMIN H. CLARK, a citizen of the United States, residing at Plymouth,.in the State of Ohio, have invented a new and useful Improvement in Covers, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

My inventionv relates to a cover and. more particularly to a type of transparent cover such as has come into popular favor in retail grocery stores and possibly elsewhere.

As is wellv known many articles of food are sold from a bulk jar or receptacle the seal of which has been broken. While it is desirable to keep such containers covered when nothing of the contents is being sold, it has recently been recognized as also desir able that such temporary covers be transparent, so that in case there are a number of jars of similar shape or size having different contents the character and amount of the latter may be known by a glance through the cover. Glass covers have been em ployed, but they are so likely to become broken that the transparent feature has been preferably supplied by the use of celluloid or ising glass, both of which are of course flexible and sufliciently transparent. However, both of these transparent substances not being strong, are subject to fracture, especially if carrying a handle at the center as some now on the market do.

The object of my invention is to provide a cover employing an upper surface of either ising glass or celluloid or some equivalent flexible and transparent substance, but to reenforce such transparent sheet of flexible material against the strains to which it would otherwise be subjected by a pull on a handle or knob at its middle section. I am well aware that reenforcing members of infinite variety have been used, but believe that as applied to a cover of the character stated the scheme amounts to invention which is novel as well as useful.

Adverting to the drawing:

Figure I is a side elevation of what may be considered a pickle jar provided with a cover embodyingmy invention.

Figure II is a top plan view of Figure I.

Figure III is a vertical section through the middle of the cover with only one part shown in elevation.

. ring 3. is anupper annular 'spectively. Such washers are 11 1922. Serial 1a. 552,eeo.

Ajar 1 is provided above'with airound,

neck 2 around the outer side ,of which the depending ring 3 of a cover is to fit. Bent around, and secured to the upper edge of the rim 4. Crossing each other at the middle and abutting, and if desired brazed or otherwise secured to the underside of the rim 4, are a pair of metal strips 5 and 6. Underneath the strip a round sheet of celluloid 7 is fitted having their ends within the ring 3. Two archedwashers 8 and 9 abut the middle of the strip 5 and the middle area ofthe round celluloid strip re- .eld in position and are adapted tightly to clamp-both metal strips andsheet together in conjunc--.;

tion with a handle 10 through which is passed a machine screw 11, which latter falso passes through bothwashers, both strips and the center of the sheet, wherebyla nut 12 may be screwed upon the inner projecting end of.

such screw;

As will be readily understood, any pull exerted on the handle 10 purposed to lift the cover will involve strains, but these will be communicated to the metal strips and thus protect the transparent sheet against fracture which frequently occurred with prior covers of this nature.

I claim 1. A cover comprising a frame,'a transparent member disposed in said frame, a stiffening piece extending across said frame, and a handle secured to said piece.

2. A cover comprising a flanged frame, a

transparent member fitted within the flange I of said frame. a stiffening piece extending between the flanges of said frame, and a handle secured to said piece.

3. A cover comprising a frame, a flexible and transparent member disposed in said frame, a stiffening piece extendingacross said frame adjacent said member, and a handle secured both to said member and to said piece.

4;. A cover comprising a flanged frame, a

flexible and transparent member fitted within the flang of said frame, a pair of crossed stiffening pieces extending between the flanges of said frame adjacent said member, and a handle secured both to said member and to said pieces.

5. A cover comprising a ring-of angular cross section, a sheet of transparent flexible material fitted in said ring, a stiffening structure placed against one side of said material, and means for fastening said material and structure together.

6. A cover comprising a ring provided with an annular flange, a round sheet of transparent flexible material fitted within said flange, a stiflening structure placed against one side of said material and extending beyond the edge of said flange, and means including a handle for fastening said materialand structure together.

' 7. A cover comprising a ring provided with an angular flange, a round sheet of transparent flexible material fitted within said flange, two crossed metal strips placed against one side of said material and overlapping said flange, and a handle having a portion passed through the point of crossing. of said strips and through said material whereby thecover may be lifted without fracturing said material.

8.v A cover comprising a frame having an aperture, a flexible transparent sheet closing the aperture in sald frame, a stiffening piece disposed against said sheet, and means for securing said sheet and piece together.

9,'A cover comprising a flanged frame having an aperture, a flexible transparent sheet closing the aperture in said frame, a

stiffening piece wedged between opposed flanged portions of said frame, and means for securing said sheet and piece together at the middle of the aperture.

10. A cover comprising the combination of a frame, a flexible transparent sheet fitted in saidframe, a reinforcing structure bearing against said frame and covering only 21.

portion of said sheet and a handle permitting said structure to be lifted to draw the cover along with it Without exerting a fracturing strain upon said sheet.

11. A cover comprising a frame surrounding an opening, a transparent member fitted in said frame and adapted to close said opening, and astiifening structure extending across said frame including a handle.

12. A cover comprising the combination of a frame surrounding an opening, a trans-- parent sheet fitted between opposed walls of said frame, a stiffening. structure less than the size of said opening (and engaging spaced portions of said frame, and means for clamping'said sheet and structure together and adapted to'serve as a handle.

13. A cover comprising a frame surroundwhereby the cover may be lifted without strain upon. said member.

, 14. As a unitary structure, a cover comprising a frame surrounding an opening, a reinforcing device carried by said frame and extending across said opening and a transparent sheet fitted in said frame so as to close said opening. v
